Experience w/product: I own it

Reviewer's Background: Active Musician

Reviewer's Play Style: Rock, Alternative, Country, etc

I was really excited to have a tuner with a metronome with a tap feature, and this does that very well. However, no back light, and the screen is very dark and hard to see if not under direct light, does have two tuning lights - fortunately the tu-2 is my normal stage tuner. Overall, overpriced for a backup tuner and nome.
